らつきを生じる。Configuration of conventional examples and their problems Defrosting of frozen foods by microwave heating is completed in an extremely short time, resulting in good quality after thawing, and has been put to practical use more widely than ever before. Here, we will be talking about the so-called thawing cooking method, which involves heating cooked foods all at once after thawing them, such as frozen cooked foods and frozen vegetables such as Mitsu Vegetables.
Conventionally, such defrosting cooking methods generally involve heating at a constant power from defrosting to cooking. Then, using a gas sensor or the like, it detects when the food is heated and automatically finishes cooking. This conventional thawing cooking method requires less heating time, but on the other hand, cold spots tend to appear in the center of the food, and uniformity is lost in areas that start to melt early and areas that start to melt slowly, resulting in temperature fluctuations. Even if there is no difference in the quality, the problem is that the finish is sluggish. Also, in such a method,
The detection time of the gas sensor also included the time during the thawing stage, which takes several times as long as cooking, and this became a factor of instability and variation. For example, if the frozen state of food varies, the time required to defrost it will vary considerably, but the time required for cooking after thawing is finished will not change much. Therefore, in this method of determining the total heating time based on the time from the start of heating, the finished cooking temperature varies greatly.

調理を実現できる。Structure of the Invention In order to achieve the above object, the high-frequency heating device of the present invention has a single key for commanding thawing cooking, a weight sensor for detecting the weight of frozen food, and water vapor and gas generated from the object to be heated. First, the frozen food is thawed at low output for a time calculated according to the weight of the food, then the output is increased to increase the temperature of the food, and when thawing is complete. The system is configured to count the time from when a predetermined amount of steam or gas is detected from the object to be heated by a gas sensor, and determine the remaining cooking time based on this counted time, and calculate the temperature difference after thawing and cooking. It is small and can realize automatic defrosting cooking with excellent homogeneity.

A door body 2 is pivotally supported on the front surface of the main body 1 so as to be freely openable and closable, and an operation panel 3 is arranged. An auto key is provided on the operation panel 3, and a thawing/cooking key 4 according to the present invention is provided therein.

ネトロンに給電されて制御される。 FIG. 2 is a block diagram showing one embodiment of the configuration of the present invention. Commands input from the thawing/cooking key 4 on the operation panel 3 are decoded by the control section 5. Then, the control unit 5 starts defrosting and cooking the frozen food, which is the object to be heated 7 placed in the heating chamber 6 . The heating is controlled by being supplied with power via a driver 8 to a magnetron serving as high frequency generating means 9.

した食品の誘電損失は材料によらず一定であるこ
とによる。つまり肉でも野菜でも冷凍されれば、
その解凍タイムは重量だけで決定できる。 As for heating, thawing is first performed using low power, and then cooking is performed using high power. Thawing is time-controlled based on the weight of the frozen food 7 on the tray 11 detected by the weight sensor 10. This is because the dielectric loss of frozen food is constant regardless of the material. In other words, if meat or vegetables are frozen,
The thawing time can be determined solely by the weight.

される。気体センサ１２は蒸気やガスに反応し、
特性が変化するので、食品の調理が完了した時点
を検出することができる。 When thawing by weight is completed, the microwave is then switched to high output and the cooking begins. Once thawed, time control is no longer possible as the dielectric loss of the food differs depending on the material. In other words, even if meat and vegetables have the same weight, the cooking time is very different, and cooking time cannot be determined based on weight, as is the case with thawing. Therefore, the gas sensor 12
This is done automatically using A fan 13 serving as ventilation means exhausts steam generated from the food 7 to the outside of the machine, and a gas sensor 12 is disposed in this exhaust guide 14. The gas sensor 12 reacts to steam or gas,
Since the properties change, it is possible to detect when the food is completely cooked.

As the gas sensor 12, a gas sensor manufactured by Figaro, a humidity sensor "Hyumi Ceram" manufactured by Matsushita Electric, or an absolute humidity sensor "Neo Huyumi Ceram" can be used. Reference numeral 15 is a detection circuit for these sensors, and reference numeral 16 is a motor that rotates the mounting plate 11 to improve uneven heating.

Diagram a shows the microwave output, and diagram b shows the amount of steam generated from the food being heated. Heating consists of a defrosting mode "DEF" and a cooking mode "COOK", and the defrosting mode is further divided into four small modes. First, at T1 , the microwave is heated at full power, and the time is calculated based on the detected weight W ( K1 : constant).
Calculated by In this mode, the temperature of frozen food is raised all at once, and the next T 2 is heated before the surface starts to boil locally.
mode, that is, transition to hibernation mode. T 2 time is also calculated by T 2 = K 2 W (K 2 : constant),
During this time, carryover heating is performed to eliminate temperature unevenness. The following T 3 and T 4 gradually reduce the power,
This mode advances the thawing of the center of the food while preventing the surface from boiling. T 3 = K 3 W, T 4 = K 4 W (K 3 ,
K 4 : constant) to calculate the time.

検出し、ここまでに要したタイムt5をベースに加
熱タイムT5がT5＝t5＋K5t5（K5：定数）と算出さ
れる。K5はゼロであつても構わない。 In this way, thawing is time-controlled based on the detected weight. At this time, as shown in Figure b, there is almost no steam generated from the food, and the gas sensor is useless. However, once defrosting is complete and the next time the cooking mode is switched to "COOK", the weight sensor is no longer useful. In other words, as mentioned above, the dielectric loss of thawed food varies greatly depending on the material, so it is no longer possible to control the time like thawing. Therefore, during the cooking mode, a gas sensor is used to detect the point in time when a predetermined amount of steam Δh is detected from the food, and the heating time T 5 is calculated based on the time t 5 required so far as T 5 = t 5 + K 5 t It is calculated as 5 (K 5 : constant). K5 may be zero.
このように本発明の解凍調理は、重量センサと
気体センサとを用いて、各々の長短をうまく活用
し、解凍と調理の２モードでこれを上手に自動加
熱できる。 In this way, the thawing cooking of the present invention uses a weight sensor and a gas sensor, making good use of the advantages and disadvantages of each, and can skillfully automatically heat food in two modes: thawing and cooking.
